turboquant_plus

TurboQuant Plus is a quantitative trading platform for building and backtesting trading strategies. Python-based with support for multiple data sources and strategy templates. If you're developing algorithmic trading systems, this provides the framework for strategy development, historical backtesting, and performance analysis.

Fully free, no paid tier.

The catch: documentation and community are primarily in Chinese. Quantitative trading tools require significant domain expertise in both finance and programming to use effectively. No English documentation means you need Chinese language ability or patience with translation tools. And backtesting performance doesn't guarantee live trading results. The trading platform space has established alternatives like Zipline and Backtrader with English-language communities.
